Definitions
- the invention relates to an ink supply device according to the preamble of claim 1.
- a pump inking unit for a multicolour rotary printing press has become known, each with an I ⁇ -roller-wide inking device with optionally operable ink supply pipelines and a large number of rotary lobe pumps.
- DE 197 21 235 A1 disclose ink supply devices in which outlet openings can be connected to two ink reservoirs. These ink reservoirs can be pressurized with a pressure medium.
- the invention has for its object to provide an ink feed device.
- the advantages that can be achieved with the invention are, in particular, that the printing ink can be replaced quickly and without much cleaning effort. No mechanically movable parts of a drive are required when feeding the printing ink to the inking unit.
- the invention can advantageously be used for smaller print jobs with frequently changing printing ink. The number of components that come into contact with printing ink is small.
- An inking unit of a rotary printing press exists. a. from an arrangement of several rollers, of which an inking roller 01 is partially shown. On the inking roller 01 a side frame fixed, and a slidably mounted ink supply bar 02 can be adjusted so that an annular gap 03 remains between the ink supply bar 02 and the outer surface of the inking roller 01 for transferring printing ink.
- four quarter-web-wide, separately adjustable ink feed bars 02 extend in the axially parallel direction of the ink application roller 01, each of which is assigned at least one ink reservoir, but expediently, as shown in the drawing, two ink reservoirs 04 or 06.
- Each color reservoir 04; 06 is on rails 07; 08 slidably arranged in the radial direction A to the inking roller 01, the profile rails 07; 08 on trusses 09; 11 are attached.
- Each of the ink reservoirs 04; 06 can be used as an alternative to the ink supply for the inking roller 01, in particular when the ink supply of a printing ink has to be renewed "on the fly" or another printing ink is subsequently provided.
- the ink supply container 04 has an ink supply space 13 which can be filled with printing ink 10 and provided with an outlet opening 12 and which, separated by a color slide 14 which can be moved back and forth in a plane 15, borders on a printing space 16. Both spaces 13; 16 have the same cross-section, on the contours of which the color slide 14 rests.
- a supply line 17 for pressure medium, for. B. Compressed air is provided, which leads to a quick coupling 18 near the color bar, the first part 19 of which Ink reservoir 04 and the second part 21 is connected to the ink supply bar 02.
- the outlet opening 12 also opens into a quick coupling 22 near the color bar, which is also constructed like the quick coupling 18.
- the second part 21 of the quick coupling 18 located in the ink supply bar 02 is connected via a line 23 to a directional valve 20, which in turn is connected to a central pressure supply 24, e.g. B. for compressed air.
- the second part of the quick coupling 22 is connected via a check valve 25 and via an upper feed line 26 for a distributor line 27 running in the axis-parallel direction for the cross-conveying of the printing ink 10.
- the distributor line 27 leads to a number of three to ten, preferably five, outlet lines 28 per%-wide ink supply bar 02.
- the outlet lines 28 each end in an outlet opening 29 directed towards the annular gap 03.
- the ink supply bar 02 has an alternative connection for the second ink reservoir 06.
- second, color bar-fixed parts 34 of a lower quick coupling 37 are connected to the central pressure supply 24 via a lower, first connecting line 38 via the directional control valve 20.
- Second ink box-fixed parts 34 of an upper quick coupling 36 are connected via a feed line 41 to the distributor line 27, which runs in the axis-parallel direction of the inking roller 01, for the transverse conveying of the printing ink 10.
- This distributor line 27 in turn leads to five lower outlet lines 28 of the% web-wide ink feed bar 02.
- the lower ink reservoir 06 has an ink bag 46 which is located in a printing space 44 and can be filled with printing ink 10.
- the ink bag 46 is by means of pressure medium 24, for. B. compressed air is arranged compressible and has an outlet opening 47 for the printing ink 10 directed towards a first end of the ink reservoir 06 near the ink bar.
- the outlet opening 47 is connected to a first part 48 of the lower quick coupling 36.
- a connection line 49 fixed to the reservoir is provided, which connects the pressure chamber 44 to a first part 48 of the lower quick coupling 37 for introducing compressed air.
- the function of the first ink reservoir 04 is as follows: The z. B. through the outlet opening 12 filled with ink upper ink reservoir 04 is moved by means of the handle 51 on the rails 07 in the radial direction A until the quick couplings 18; 22 are connected. By supplying compressed air to the pressure chamber 16, the ink slide 14 is pressed in the direction of the ink supply bar 02, so that the printing ink 10 exits into the annular gap 03 via the outlet opening 12 and via the lines 26 to 28 and the corresponding outlet opening 29.
- a level indicator for printing ink can e.g. B. be created in that a slide member 52 consists of electrically conductive material and when emptying the ink reservoir 13 with first or second proximity switches 53; 54 comes into contact, which triggers a corresponding signal.
- the second ink reservoir 06 can be put into operation by applying compressed air to the pressure chamber 44 via the connecting line 49.
- the compressed air supply to the upper ink reservoir 04 is then interrupted by the switching of the directional valve 20.
- the first feed line 26 and the second feed line 41 are alternately opened or closed.
- the ink supply containers 04 or 06 can each be designed with a paint slide 14 or with an ink bag 46 and can be operated with compressed air. It is also possible to design the pressure medium 24 not only in gaseous form but also in liquid form, ie to use water or oil.
- the pressure medium always acts indirectly on the printing ink 10, i. H. with the interposition of the slide 14 or the paint bag 46.
- the printing ink 10 is conveyed to the outlet opening 29 without the interposition of a pump.
